Learn about audio choices when using Adobe Connect

When and how to use integrated audio features most effectively

Web conferencing has emerged as a critical communication tool for today’s organizations. It's rapidly becoming as essential for business professionals as email and voice communications. However, some existing web conferencing solutions have fallen short of the ease and effectiveness of in‐person meetings. They’re complex and difficult to use, and they lack real‐world functionality. In addition, without reliable, high-quality audio, web meetings don’t work.

Adobe Connect is different because it allows business users to easily communicate and interact with geographically dispersed colleagues and customers in real time. It offers high‐impact presentation and collaboration tools, including screen sharing, multipoint video, integrated telephony, and white boarding. These capabilities make web conferencing a viable way to work more effectively.

Adobe Connect uses a desktop application for instant, hassle-free access to Adobe Connect meetings with anyone, anywhere. It lets users create personalized, easy-to-remember URLs that never change. Meeting participants can share their screens for collaborative work sessions with colleagues or one-on-one meetings with customers at the click of a button. Adobe Connect makes it easy to engage small and large audiences with video, animations, and software simulations. Adobe Connect is great whether in live events or meetings recorded for later, on-demand viewing. An intuitive interface makes it simple to organize meeting workflows and customize the appearance of meetings and events to reflect corporate branding.

Today, Adobe Connect users have various technology options to enable audio communication with web conferences. These options include Voice over IP (VoIP) communication, advanced integrated telephony, Universal Voice, and hardware-assisted options.

This white paper provides an overview of the options in the meeting user interface. It explains which features work with which audio provider partner. It also covers use cases that represent a majority of web conferencing scenarios, and outlines the best practices to consider.

Adobe Connect VoIP

VoIP‐based conferencing is similar to telephony‐based audio conferencing in that it allows two or more individuals to communicate in real time. But unlike audio conferencing, VoIP communication travels exclusively over IP networks. Meeting participants use their computer microphones and speakers—or external microphones and speakers connected to the computer—to communicate with other participants, without any telephony infrastructure required. Adobe Connect provides high-quality VoIP out of the box. It offers features such as echo and noise cancelation, silence detection, and an easy audio setup wizard.

VoIP in the Adobe Connect user interface

In the Adobe Connect user interface, you can choose to restrict microphone rights. Or, you can grant microphone rights to everyone using the Enable microphone rights for participants feature.

If you choose to restrict microphone rights, then only the hosts and presenters automatically can use the microphone to broadcast audio to meeting participants. In this mode, for participants to speak, it's necessary to explicitly grant them microphone rights.

If you choose to grant microphone rights to everyone, all meeting participants can turn on their microphone and begin broadcasting their audio.

Restrict microphone rights for all meetings except for meetings with a small number of attendees.

Special considerations when using VoIP

High-fidelity, full-duplex audio broadcasting within Adobe Connect doesn’t incur any additional cost per attendee. But before using VoIP, meeting organizers should ensure the following items for all participants:

  • Comfortable with VoIP—VoIP has been around for years. But, it's possible that some users aren't familiar using it as their primary method of audio communication during a live event.
  • Necessary hardware—Your audience should have internal or external speakers and microphones. When using VoIP, it’s a good idea to include a note about the audio requirements in your meeting invitation.
  • Sufficient bandwidth—Consider the potential bandwidth impact that VoIP could have on your meeting and each participant’s experience.

For the best experience, make sure that all participants in a VoIP‐based meeting install the Connect Meeting application for desktop.

Universal Voice

In certain situations, some attendees want to use telephony‐based audio, while others want to use VoIP. This scenario is a fairly common in web conferencing meetings or seminars that span countries. A toll‐free number could be available to callers within the United States, but only toll numbers are available to participants in other countries. Providing participants with the option to choose either telephony-based audio or VoIP for the same meeting is best when you are holding an important or large event such as a customer-facing webinar. In these events, it's possible that you don’t have much insight into the connection speeds and configurations or your attendees.

Starting with version 7.5, Adobe Connect offers Universal Voice, a feature that streams virtually any telephone conference into an Adobe Connect meeting. It creates a one-way bridge between the telephone conference and the VoIP functionality of Adobe Connect. Adobe Connect lets you integrate with any audio provider or teleconferencing platform. You can record telephone-based audio along with your web conference and then stream the telephone-based audio to VoIP participants. Participants can choose to dial in with their phones or listen via their computer speakers. Giving participants this choice can help reduce telephone charges for the meeting participants and host because fewer people are dialing in. In addition, hosted customers do not need to purchase new services or hardware nor worry about incompatibility. (On-premise customers do need a Session Initiation Protocol (SIP) gateway.)

Using Universal Voice offers the following benefits:

  • Reaching a wider audience—Because you can offer both connection methods, participants can choose the audio option that best suits them.
  • Flexibility—Meeting hosts can use any audio-conferencing provider, not just providers that are Adobe partners. They can even use multiple providers.
  • Reduced phone toll charges—Participants can opt to use VoIP rather than dialing in and possibly incurring telephone charges.
  • Instant availability—After the meeting, the recording of the event is available immediately. Post-processing to sync up the audio with the event is unnecessary.

Universal Voice in the Adobe Connect user interface

When setting up a conference, the meeting host uses the wizard to configure any Universal Voice audio provider. The host can set up the conference number, dual-tone multi-frequency (DTMF) call tones, and pauses for dialing into the conference. A meeting host can configure Adobe Connect to use any audio provider.

Advanced telephony integration

Telephony is, by far, the most broadly accepted form of audio conferencing. Geographically dispersed individuals require only a telephone to participate in a web conference in real time. So, there are few barriers to an integrated web and audio conferencing experience. Integrated recording capability ensures a successful archiving experience when audio and web conferencing activities are synchronized.

Adobe has partnered with several audio-conferencing providers to provide advanced call features that give meeting users greater control over the complete audio and web meeting experience. Call controls, audio recording options, participant management, breakout rooms, and operator assistance are all available from Adobe’s audio partners.

Some of the benefits of advanced audio telephony integration include:

  • A unified workflow for scheduling, notifying, and attending web and voice conferences
  • The ability to completely control the teleconference call through the web conference interface
  • The convenience of recording a single, synchronized archive of the Adobe Connect meeting and audio from the teleconference

Visit www.adobe.com/products/acrobatconnectpro/partners/#audio for a complete list of audio teleconferencing partners.

Advanced integrated telephony in the Adobe Connect user interface

When setting up your meeting in the Create Meeting wizard, choose Include Audio Conference Details with This Meeting. (If this option is not available, it could be necessary to set up your profile with your teleconference information. Contact your Adobe Connect administrator for more details on including a supported teleconference system in your account profile.) Teleconference information is included in the meeting invite, and participants can also have the teleconference dial their phone directly without entering any passcode information. The meeting automatically records audio from an integrated teleconference. To hear the audio from the meeting, make sure that all participants are connected to the teleconference.

Hosts and participants have many convenient call controls in the Adobe Connect user interface.

Call controls for meeting hosts:

  • Start or stop the teleconference—The host can initiate and terminate a teleconference with a click.
  • Synchronized web and voice recording—The “record meeting” function records the web conference and teleconference simultaneously to create a single, streaming archive of the meeting.
  • Dial-out to participants—The meeting host can dial out to existing participants in the web conference or add phone-only participants and call them to join the conference.
  • Change volume for selected participants—The meeting host can increase or decrease the volume level for each attendee.
  • Mute participants—The meeting host can mute all or selected meeting participants.
  • Put participants on hold—Meeting participants can be put on hold if the host wants to temporarily close the floor to participants.
  • Disconnect participants—The host can remove a phone participant from the meeting with one click.

Call controls for meeting participants:

  • Call me—Meeting attendees can enter their phone number and have the teleconference call them back. They don't have to dial the conference number and enter the passcode through the phone.
  • Mute me—Attendees can mute and unmute their phone lines.
  • Who’s speaking indicator—Attendees don’t have to wonder who’s speaking in the teleconference. A visual indicator next to the attendee’s name makes it easy to identify speakers.

Adobe Connect includes a telephony integration software development kit (SDK), which allows for custom development. Assuming your telephony bridge or service has published APIs, the SDK allows you or an authorized partner to build a connector between Adobe Connect and the telephony system. APIs allow for the management of the conference through call control, synchronization of recording events during the meeting. They also allow the convergence of audio and web recordings on the Adobe Connect server.

Special considerations when using advanced integrated telephony

Before using telephony, meeting organizers should take into account the following points:

  • Cost to the organizer—Audio-conferencing systems require users to pay additional fees for the service or technology.
  • Cost to users—For geographically dispersed, international locations, telephone‐related fees can be expensive for the meeting host (if using toll‐free numbers) or the meeting participants (if they required to dial long distance).
  • Limited capacity—Some teleconference audio providers support a fixed number of participants on a call. Ensure in advance that your provider supports your required number of dial-ins.

Hardware options

Meeting organizers can use a number of third-party devices to integrate VoIP and telephony and automatically capture audio or to enhance the quality of event recording. However, beginning with Adobe Connect 7.5, it's unnecessary to use hardware to integrate VoIP and telephony. Universal Voice enables this integration out of the box.

Improving recorded audio quality

Many customers use Adobe Connect to broadcast live, in-person events from venues such as convention centers or conference rooms. There are a number of best practices that can help ensure an optimal experience. One such best practice is using a dedicated computer with an audio capture card. Otherwise, meeting hosts could use the host computer’s internal microphone, often resulting in poor audio quality.

The Shure X2u XLR-to-USB Signal Adapter (www.shure.com/ProAudio/Products/Accessories/ us_pro_X2u_content) allows users to take a high-quality audio feed from the mixer and go straight into the computer with a high-quality signal via USB. With this device, users don’t have to depend on the quality of the computer’s sound card or internal microphone. No audio quality is lost through the conversion, and the device supports professional XLR inputs and provides phantom power for stand-alone microphones. It works with both Windows® and Mac OS, and no drivers are required.

Using hardware to integrate VoIP and telephony

Customers who want to use hardware to integrate VoIP and telephony as opposed to using Universal Voice, the out-of-the-box hybrid approach first introduced in Adobe Connect 7.5, have a few options.

Simple method—Presenters dial into the teleconference at the same time they broadcast their voice using Adobe Connect VoIP with a headset or microphone. They are essentially transmitting audio via the phone and the headset at the same time. This method is the least sophisticated.

Advanced method—A more sophisticated method that is easier for situations with multiple presenters involves a third-party device that connects the telephone to the computer’s audio input. An example is the THAT-2 from JK Audio. Using this method, a host calls into the teleconference and uses a device to send the teleconference audio into the computer’s line-in input. Presenters dial into the teleconference, and the host broadcasts the teleconference audio over Adobe Connect using the Talk button in the Layout Bar. This method allows a single person to manage the simulcast and reduces the complexity for presenters. It is important to note that it's necessary that everyone speaking on the call is dialed in to the teleconference. Think of the VoIP as a one- way stream, where users can hear audio but not speak. To view a tutorial on how to use the THAT-2 devices with Adobe Connect, visit www.connectusers.com/tutorials/2009/03/that2/index.php.

Professional method—If you are willing to invest more money in a combined VoIP and telephony solution, using a capture card and mixer provides the highest level of control and the best possible audio quality.  The Adobe Connect Event Services team uses ViewCast Osprey 230 capture card teamed with a Polycom mixer. You use the software included with the Osprey card for the audio control, in concert with your computer and meeting controls for optimal performance. To learn more about the Osprey capture card, visit www.viewcast.com/products/osprey-230.

Use cases

Adobe Connect is a flexible web conferencing solution that supports various scenarios. This white paper focuses on the audio communication requirements of the three common use cases, virtual classrooms, web conferencing, and sales and marketing seminars.

Virtual classrooms

  • Events can be live or on demand.
  • Live sessions are similar to in-person classroom environments, which sometimes involve one   presenter and many learners, and sometimes consist of collaboration among participants.

Web conferencing

  • Events involve two or more individuals collaborating, but generally not more than 50           participants.
  • The interactions are similar to in-person interactions in a conference room.

Sales and marketing seminars

  • One individual presents to many participants.
  • These events are similar to lectures or seminar-style, in-person meetings.

When determining which conferencing option is best, the two biggest considerations are the size of the meeting and the desired level of interactivity. The following table provides an overview of the strengths and weaknesses of the different technology options for supporting audio communication.
